Crow Horse 8 #1 Posted October 3, 2009 What is the diameter of the PTO clutch disk for a B-80, part #'s 103817 or 94-6650 ??....... What other model's will use the same disk? Mine has cracked and lost a segment of the friction material. Still works, but I'd like to get it right..... Thanks.... Share this post Link to post Share on other sites
Crow Horse 8 #2 Posted October 4, 2009 With a lot of searching, I found my calipers to accurately measure mine and it's 6 3/4" diameter....... :scratchead: Share this post Link to post Share on other sites
hodge 6 #3 Posted October 4, 2009 Most any will work. I pulled a clutch disc off a late 60's Raider 9 and put it on my 88 520. Worked perfect up to the day I sold it. Share this post Link to post Share on other sites
Don1977 604 #4 Posted October 4, 2009 I have a 1977 C-120 and had to replace the clutch disk. Got a new one from Wheel Horse and it caused the C-clips to ware out. I found the new metal disk to be thiner than the old was the problem. I then made a 16 gage spacer to put behind the new disk, it's a real trick to get it all lined up and installed. I have not had to change C-clip since. I wore out three sets of C-clips before I discovered the difference in thickness. So If you change to a different disk check the thickness of the steel disk.
